ABSTRACT: Intelligent transport systems (ITS) are advanced application in which information and communication technologies are applied in the field of road transport, including infrastructure, vehicles and users, and in traffic management and mobility management, as well as for interfaces with other modes of transport. Intelligent transport systems technologies applied in car navigation, traffic signal automatic number plate recognition or speed cameras to monitor applications, such as security CCTV systems parking guidance & information systems, weather information, bridge deicing systems. In this technology, wireless communications are explained as short range & long range communication. Recent advances in vehicle electronics have led to a move toward fewer, more capable computer processors on a vehicle. "Floating car" or "probe" data collection is a set of relatively low-cost methods for obtaining travel time and speed data for vehicles. We explained this floating car in three methods to obtain the raw data- Triangulation method, Vehicle Re-identification, GPS based methods and inexpensive intelligent beacon sensing technologies, have enhanced the technical capabilities that will facilitate motorist safety benefits for intelligent transportation systems globally. Sensing systems for ITS are vehicle- and infrastructure-based networked systems, i.e. intelligent vehicle technologies. Bluetooth road sensors are able to detect Bluetooth MAC addresses from Bluetooth devices in passing vehicles. Emergency vehicle notification systems is the most important application of ITS.
INTRODUCTION: Intelligent transport systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use
